This manuscript contains several texts relating directly to Abingdon Abbey, for which it must have been made. These include a cartulary, a list of church officials, a customary (recording details of how various actions should be performed, such as the initial of a novice), a list of lands belonging to the abbey, and so on. These 'puzzle' initials (so-called because the red and blue or green parts interlock like pieces of a jigsaw puzzles) introduce, first, a passage about the rebuilding of Abingdon abbey (referred to as 'this church'; and with 'Abbendonie' written in capital letters, three lines from the bottom of the first column); and second, a copy of a charter of King Eadred, dated 955.
